Production and processing of pre-impregnated thermoplastic tapes by pultrusion and compression moulding

Although there is no doubt that composite materials are the future of lightweight structures and components, most composites currently produced made from thermoset polymers, which not able to be recycled or reprocessed. In contrast, thermoplastic polymers offer possibility recycle reprocess when combined with a fibrous reinforcement, provide interesting mechanical properties. This work reviews production two pre-impregnated in tape form, one on new prototype equipment developed our laboratories. The method for described, prepregs presented here were subjected processing techniques. first method, pultrusion, an efficient autonomous produce profiles, marking itself as continuous cost-effective way these materials. Pultrusion bars then heated compression moulding, process allows obtain more complex-shaped parts. second relatively simple was used laminates. pultrusion laminates testing evaluate levels consolidation final material. A microscope also carried out analyse dispersion fibres polymer, well amount voids present composite.
